Hellou, i have a litlle problem. I have method for Raise terrain. It works good if i have terrain width 1000 and terrain length 1000, if i make terrain for example 5000x5000 brush is same but hill is 5 x bigger or if i make terrain 200x200 brush is same but hill is 5 x smaller… I add here two methods where i make hills or dig but i dont use terraindata.size or something like that, so i dont understand. Thanks for all help
